2008 6 speed C4S (997.1) with 57k miles, car is new to me but no history of engine replacement.
Clutch was replaced a couple weeks ago, no signs of leakage near the IMS bearing (it has the non-easily replaceable IMS bearing being a 2008).
Recent oil change and filter inspection revealed a few non-ferrous (aluminum) flakes and that's it.

2005 early production date
10/04. The recent posts on this discussion forum make me worry now. The number of "yes, failure" posts on the running tally since it began is now over 6%. That's high and probably as the years go by the number will only increase.
I live in FL and the warm weather most of the year keeps the average ambient temperature around 70 degrees in the morning opposed to much lower if I lived up north. So starting the engine, the oil is less viscous and the metal less cold so the oil gets to operating temperature quicker (smaller delta H) and proper lubrication occurs quicker and possibly less wear on the ims bearing.
The only problem with this theory is my two friends who live near me owned 996s each and had their ims fail; one at 60k miles and the other at 89k miles. 😔

I just got the production date on the car (and for the failed original engine), October 2004.

2007 997.1. 40,000 miles. No problems.

So my 2006 997S has 60k miles right now and from time to time when i start it up i hear a fast grinding sound. Kinda like a spinning sound. Any Idea from past IMS issues if this is a sign of IMS failure.

I'd do an oil change, inspect the filter media, and also drop and inspect the oil pan for any debris.
